    Economics Degree

    Unfortunately, we can't just buy a tool by name, in most cases . . . we have to study Economics, and keep track of which corporate giant now owns our favorite tool company.

    As was pointed out in an earlier reply, DeWalt was bought by Black and Decker -- at which point the bean counters took control of quality control. My DeWalt tools all pre-date that corporate takeover (early-1990's), and are all working well, and used on an almost daily basis. Likewise my Metalbo (circa 1988) grinder, and my Bosch (circa 1990). My Milwaukee grinders (paddle switch) have held up well, but run on the heavy side.

    My Metalbo came from a trade with a mason who liked the pretty yellow of a new DeWalt I had. A little shop air to blow the dust out, and it has performed flawlessly for me for over fourteen years. Some day I'll sandblast the case and repaint it--it deserves a place of honor.

    There's no question about this: you can't beat using quality tools.

Paddle switch is best as the top switch ones tend to lock in on when you don't want it to.
      Steve, quick question. I haven't yet welded AL yet, but have been trying to read up and learn as much as I can from this forum, and one thing that I have gotten loud and clear is that when welding AL, it has to be clean enough to eat off of. I noticed you mentioned that you use an auto oiler, wouldn't there be an issue with contaminating the joint, or do you only use this in the early stages of prep work, where you have to go over it with other things before the weld? Sorry if it seems like a basic question, just trying to understand. I do get the shavings in the electric motor part, so the air idea itself makes sense, just wondering about contamination.

      Thanks!

          Ive had the same Hilti 4 1/2' for twenty years. Ive beat on it, dropped it clogged it with concrete dust, blown all the dust out, filled it up again and again.... I think ive made at least fifty pounds of metal dust with it... another fifty of aluminum dust too and it just keeps going.. TWENTY YEARS!!! and im the second owner. it came off a construction site were it was used to smooth out concrete walls.... so yeah.. HILTI is the way to go.. now tha ti may have jinxed myself... I need to go find some wood... hmm wood what does that stuff look like? anyone know..? I cant remember!
          Will it weld? I loooove electricity!

            FWIW, HILTI doesn't make their grinders. They were made by Metabo for the longest time and may still be. AEG has made some of their stuff as well. German engineering at its best.

            I have a 5" Metabo that is still as strong as the day I got it....in '89. I also have several DeWalts. They do the bulk of my work and have held up very well. I have had no troubles with them... and no, I am not going easy on them either.

              I feel somewhat qualified to comment on this subject. Pic shows a three or four year accumulation . . . note plenty of B&D's, Dewalts, Milwaulkee's . . . Just a couple years ago, I threw at least this many, probably more, into my dumpster . . .

              Only brand I personally have found that holds up, in the 4 1/2" to 5" range, has been Bosch . . .

                I have the Dewalt and the Milwaukee 4 1/2" grinders and both are fine grinders.My choice would be the Dewalt for comfort and performance though.But one thing that I have learned is that people want a 4 1/2" grinder to do the job that a 9" grinder should be performing.I understand that not every body has a big grinder but be realalistic in what you are asking from your grinder.The right tool for the job always pays off.

                  i really like my porta cable grinders. they have held up the best and for the longest.
                  i think cajuncat makes an excellent point about keeping in mind its a 4.5" grinder and not to expect it to do the job of a 9" one. i only have 4.5" grinders and at times think i should have a bigger one but make due with the 4.5" i have.
                  twisted wire cup brushes seem to rattle the crap out of a grinder and have been the downfall of many of my little B&D grinders. i have them on my porta cables now with better results but can tell its a tuff job for any grinder.
                  thanks for the help
                  ......or..........
                  hope i helped

                    grinders

                    I have many occasions to remove parts from the aforementioned Muskox in order to do details on the bench and then replace them on the sculpture...such as the underside of the horns.
                    This is like building a car...hard to get underneath and impossible to lift.
                    I use the Dewalt grinder to cut and fit.
                    Having used several other brands including Makita, I keep a B+D in reserve but I call them 'disposable grinders' so I don't feel so mad when it quits.
                    A nine inch would torque me across the shop.
                    More photos soon of the Muskox...summer slowed me down.
                    Hope you are all working hard and liking it.

                      It truly is unfortunate that we now live in what is becoming more and more of a disposable world. I'm quite sure it all boils down to dollars. If something is made to break down, another can be sold in order to maximize profit. Sigh.
                      Im glad my Hilti (not made by said company) is standing the test of time and abuse.

                      Someone once said to me: " a poor man cannot afford to buy poor quality"
                      I think I tend to agree impoverished or not.
                      Will it weld? I loooove electricity!

                        most of the time a 9 inch grinder wont fit, if i could fit a 9 incher, believe me i would use one. faster removal, less heat, and less time changing stones or wheels.

                          It's Hilti

                          I'm new to posting but not new to this MB. Been coming here for a long time! In any event I think everyone has an idea of what works best for them and what does not. I have been melting steel for years and have gone the distance with just about every tool mentioned here. For me, when I decided to give up the buck and try Hilti (MADE BY HILTI I've been to the plant in Lichtenstein and Düsseldorf) my hand tool problems just went away. I think if a contest were to be held on who can or who has abused their tools with great vigor, I would shine on top. I usually don't spend this much time writing about what I consider "little things" but for all that Hilti has done for me, they deserve recognition as being the finest power tools you can get your hands on. Yes they are expensive, but for me I can't afford not to have the best.

                            welder-one i hope i didn't come across the wrong way about the 9" grinder.i totally understand that the grinder doesn't always fit.i find myself alot of times that the smaller grinder doesn't fit either and i have to use my die grinder to get in some spots.its just that i see with some contractors that we bring in at work the guys using the 4 1/2" grinders instead of something bigger and then complains on the time it takes or that their grinders are getting hot.i work in heavy equipment repair so there is alot of use for the big grinders and i understand in other fields they may never have the reason for a bigger one.it all goes according to the type of work that you do.so i'm sorry if i came across the wrong way.

I do have a Bosch 7 1/4" circular saw that has been great, Cuts 1/8: aluminum easy

                                cajun, i wasnt being offended by your comments. only stating that if i could use a 7 or 9 inch grinder i would. i did bring my milwuake from home to prove a point, and i believe that we are going to give them a try. i would like to try the metabo, but i cant talk the purchasing lady to come off of any money until she has proof that it is a good machine. this lady and i have had rounds about stuff like this. she wouldnt allow the swap from c25 to c10 mix to allow spray transfer because "we have never used it before, why start now" i told her before we didnt have a machine that would handle it, now we do. we have the millermatic 350p. it will almost spray with c25, but not quite
